Our purpose in this report is to record the results of observations that we have made on Trichomonas vaginalis during six months. It is hoped that our observations may stimulate others to investigate this parasite.
Donné,1 in 1837, observed that a flagellate parasite is present in certain vaginal secretions. This organism has been found by more recent observers in a rather high percentage of persistent abnormal vaginal discharges. (Hausmann, 40 per cent; Hoehne, 28 per cent; Witte, 40 per cent; Hegner,2 50 per cent, and Schmid and Kamniker,3 69.9 per cent.) Nevertheless, Trichomonas vaginalis remains a mystery.
